PHYSICS MODULE 2 VOCABULARY
| Question | Answer |
|---|---|
| a system used to describe motion that gives the zero point location of the variable being studied and the direction in which the values of the variable increase | coordinate system |
| the point at which both variables in a coordinate system have the value zero | origin |
| the distance and direction from the origin to an object | position |
| the entire length of an object's path, even if the object moves in many directions | distance |
| a measure of size | magnitude |
| a quantity that has both magnitude and direction | vector |
| a quantity that has only magnitude, and no direction | scalar |
| the difference between two times | time interval |
| a change in position having both magnitude and direction; is equal to the final position minus the initial position | displacement |
| a vector that represents the sum of two other vectors | resultant |
| the position of an object an any particular instant | instantaneous postion |
| the ratio of an object's change in position to the time interval during which the change occurred | average velocity |
| the distance traveled divided by the time taken to tr4avel that distance | average speed |
| a measure of motion that tells the speed and direction of an object at a specific instant | instantaneous velocity |
